CLIP

Filed July 20, 1929 Patented Dec. 9, 1930- UNITED STATES PATENT ol-r-'ICE-N JOHN P. LYNN, F CHICAGO, ILLINOIS, ASSIGNOR 'I'O DUR-O-LITE IENCIL CO., OF CHICAGO, ILLINOIS, A. CORPORATION OF ILLINOIS CLIP `Application med J'uly 20,

This invention relates to clips for pencils, fountain pens and the like and has for its object to provide an improved clip which is cheap, simple in construction and can be readily mounted upon a pencil, pen or the like, in such a manner that the forces applied on such clip in normal use tend to jam the mounted end thereof in position.-

,Other objects, advantages and capabilities will later more fully appear.

My invention further resides in the combination, construction and arrangements of parts illustrated in the accompanying drawings, and while I have'shown herein a preferred embodiment I wish the same to be understood as illustrative only and not limiting the scope of my invention.

In the drawings,

Figure 1 is a longitudinal view of the upperend of a pencil, partly in section, with the improved clip mounted thereon,

Fig. 2 is a section on the line 2--2 of Fig. 1,

Fig. 3 is a section on the line 3 3 of Fig. 1,

Fig. 4 is a sectional detail on the line 4-4 of Fig. 1,

Fig. 5 is a sect1onal view of an intermediate part of the pencil on the line 5-'5 of Fig. 2 showing the clip in juxtaposition thereto,

Fig. 6 is a perspective view of the clip, and

Fig. 7 is a sectional detail of a pencil showing a somewhat modified clip mounted thereon.

Referring to the drawings the clip com- A prises a springy portion .10 which is curved inwardly at one end and gives into a plate portion 11 which is intended to be applied to the surface of the pencil. At its other end the springy portion 10 carries a smooth curved member, for example a sphere 12, which is adapted to engage the fabric forming the outer wall of the pocket and permit same to pass readily and safely between the springy portion 10 of the clip and the pencil body 13.

The longitudinal edges of the plate portion 11 are turned inwardly 90 to form two flanges 14, said flanges having integral therewith extensions or lugs 15 whlch are intended to extend into the wall of the pen or pencil as 1929. Serial No. 379,859.

hereinafter described. The edges of said extensions or lugs 15 may be perpendicular to therplate portion 11 as shown in Fig. 5 or they maybe oblique thereto as shown in Fig.

l7. The ends of extensions or lugs 15 are l magazine 18 or other chamber therein.

The slots 17 are somewhat smaller than the lugs 15 so that the latter have a tight drivev fit therein. The grooves 16 are also preferably somewhat smaller than the flanges 14 to assist in retaining the clip in mounted position and also to cause the outer sides of the grooves to make close contact with flanges 14 at the visible lines of contact therebetween. The difference in size between the slots 17 and the grooves 16 and the parts of the clip received therein depends upon the elasticity of the material from which the body is made. In all cases it is such that when said parts are driven into position they are held by a substantial frictlonal force and the material of the body 13 adjacent thereto, particularly the material adjacent the edges of the lugs 15, is under substantial compression so that movement of said parts is strongly opposed.

The relation of the portion 10 of the clip to the plate portion 11 thereof is'preferably such that when the latter is pressed into seating relation upon the pencil body, the springy portion 10 is bent outwardly and the ball 12 pressed against the surface of the pencil body.-

It will be readily understood that when the clip is pressed into mounted position the friction between the edges of the slots 17 and the lugs 15 strongl opposes any force tending to raise the p ate 11 directly from. the pencil body. However, the 'principal forces experienced by said plate in normal use of the pencil or the like are of a rotary nature and are exerted thereon by the curved end of the springy portion 10 of the clip. Movement due to such forces is opposed by said friction and also by a jamming effect produced between the lugs 15 and slots 17. Such jamming effect is accentuated by the state of compression of the body material adjacent said lugs owing to the tight drive iit therebetween. When the slots 417 extend inwardly and downwardly as shown-in Fig. 7 the obliquity of the sides of the slots nearest the free end of the clip receives and directly opposes the thrust due to any tendency of the plate 11 to rotate.

When the clip is pressed into position the ends of the lugs 15 preferably extend into the chamber 18. The projecting extremities of said lugs are preferably sheared off by an operation which leaves the burrs facing each other as shown at 19 in Fig. 2. Such burrs enter into the material of the pencil body and aid in holding the clip in position. It is obvious that similar burrs, or deformation or the like can be produced otherwise during or subsequent to the driving of the clip into position.

The grooves 16 and slots 17 may be formed or produced in any suitable way. Thus, they may be formed during the moulding of the pencil body. In the case of certain relatively plastic materials they may be subsequent to moulding by a male die (3o-operating with a female die on a mandrel or they may be cut out mechanically by suitable means.

I claim:
